Definitions

  • This invention relates to a pack type container for containing foods such as dressing, jam, milk, etc., or other materials, which is characterized by its structure that allows complete ejection of its content by a simple one-hand finger operation with no fear of soiling the user's fingers.
  • the former type of container has the possibility of soiling the user's fingers since the content (C) is liable to spatter out when the lid (B) is peeled off, and moreover in case the content is a viscous substance, it is impossible to take out the content entirely from the container.
  • the containers of the latter type whose examples are disclosed in U.S.
  • Patents 3,986,640, 4,493,574, 9,611,715, etc. have the defects that they are poor in barrier properties and also the materials to be contained therein are limited to certain specific ones, since the lid usable therefor is confined to a hard sheet made of a brittle single material such as hard polyvinyl chloride, polystyrene and the like because in the case of this type of containers the lid must be torn along the slit line (13) while bending the container body outwardly. Further, since tearing of the lid and ejection of the content are conducted at the same time, the content tends to spatter out and be scattered about on peel-off of the lid, causing soiling of the environment and the user's fingers.
  • Prior art document EP-A-178 918 discloses a dispenser package for flowable substances.
  • a flowable product is contained within a flexible pouch adhered to a relatively stiff sheet which is opened along a fault line or pattern with one hand by folding the stiff ends toward one another into a "V" shape.
  • the pouch is formed with a shallow duct or channel area directly behind the fault line connecting two laterally spaced pockets located on either side of the fault line to eliminate squirting or "spitting" of the flowable product upon rupture of the fault line.
  • the stiff sheet also may contain one or more protrusions displacing at least a portion of the fault line out of the plane thereof, the protrusions comprising substantially pyramidal shapes having either straight-lined or curved profiles.
  • Another object of this invention is to provide said type of container, which is capable of completely discharging two different kinds of contents simultaneously by a single opening operation, and which is high in degree of freedom for the selection of material of the container main body and the lid.
  • the present invention provides a pack type container as specified in claim 1.
  • the container comprises a lid and a container main body and is sealed at least at is peripheral flange.
  • the container main body can be bent outwardly, and by the portion for bending it is divided into two content-holding portions designed such that when the container main body is bent said two portions may be pressed by each other.
  • the lid comprises at least a mono-axially oriented film arranged such that its direction of orientation will coincide with the lengthwise direction of the portion for bending.
  • a non-sealed portion is provided at an edge portion of the peripheral flange coincident with at least one end of the portion for bending.
  • at least two slit lines for initiating tear are provided in a part of the lid which constitutes the non-sealed portion.
  • the container according to this invention includes four preferred embodiments.
  • the container is sealed only at its peripheral flange, and the two content-holding portions are in communication with each other through a space formed between the portion for bending of the container main body and the lid.
  • the container is provided with two slit lines for starting tear in the part of the lid which constitutes the non-sealed portion.
  • the first object of the present invention can be attained by a container of this embodiment. That is, according to this embodiment, there is provided a pack type container which is free of the problems of the conventional containers as mentioned above, and which is capable of completely ejecting its content by a simple one-hand finger opening operation, and which has a high degree of freedom for the selection of material of the container main body and the lid.
  • the container sealed at its peripheral flange not only is the container sealed at its peripheral flange but also the portion for bending of the container main body is sealed to the lid, and the two content-holding portions are perfectly separated from each other to constitute two independent compartments.
  • two slit lines for starting tear are provided in the part of the lid which constitutes the non-sealed portion, and the distance between said two slit lines is larger than the width of the sealed section of the portion for bending of the container main body.
  • the second object of the present invention can be accomplished by a container of this embodiment. That is, according to this embodiment, there is provided a container which is free of the problems of the conventional containers, which is capable of completely ejecting two different kinds of contents simultaneously by a single opening operation, and which has a high degree of freedom for the selection of material of the container main body and the lid.
  • the container sealed at its peripheral flange not only is the container sealed at its peripheral flange but also the portion for bending of the container main body is sealed to the lid, whereby the two content-holding portions are perfectly separated from each other to constitute two independent compartments, and there are provided three slit lines for starting tear in the part of the lid which constitutes the non-sealed portion, said slit lines being so arranged that the distance between the slit lines of both sides may be larger than the width of the sealed section of the portion for bending of the container main body.
  • the fourth preferred embodiment is identical with said third embodiment except that a cut groove or a line of perforations for cutting off the two compartments is provided along the center line in the lengthwise direction of the portion for bending of the container main body, which corresponds to the extended line of the central slit line.
  • the third object of the present invention can be realized by a container of said third or fourth embodiment.
